The invention consists as a whole in an organized hand-machine, in whichare combined a supporting-frame having a handle adapted to be grasped bythe operator and provided with a throat or channel arranged to guidestaples into the work to which the machine is: presented, a removablestaple-holder or chute` arranged to deliver staples to said throat andpro ided with a spring-impelled feeding device or follower, whereby arow of staples on said chute are pressed forward as fast as they aredriven, a driver arranged to pass through said throat and eject staplestherefrom one at a time, and a pneumatic operating device for saiddriver, whereby the driver may be forcibly depressed to driveastaple andraised preparatory to driving another staple.

The invention also consists in the combination, with a portable frameand alstapleholder or chute, a driver, rand a driver-operating devicecarried by said frame, of a pair of pineher-jaws and a fulcrum therefor,said jaws and fulcrum being reiatively arranged, as in a pair oflasting-pinehers, one jaw constituting the throat through which thcstaples are driven and the other being movable toward and from saidthroat, the arrangement being such that the operator can use the jaws indrawing v.the edge of the upper over the bottom of the last, and then,while holding the drawn-over portion of y'the upper in place, can drivea staple through the said combined throat and jaw, and thereby fastenthe upper close to the point where it is held by the jaws.

The invention also consistsn certain minor improvements incidental tothe foregoing, all

of which l will now proceed to describe and claim.

ln thed'rawings, Ct represents the stapleguiding th roat, which isformed ou or attached to the frame of the machine and projectsdownwardly theretrom, so that its lower endg,l

in which the staple-chann el a terminates, may be conveniently appliedto the surface into which the staples are to be driven, the machinebeing held by the operators hand and moved about from point to point todrive the staples whereverthcy may be desired.

'c represents the driver, attached to a driverbar c', which is adaptedto reciprocate and carry the .driver back and forth in the staplechannela. To the driver-bar is attached a pistonldpwhich is fitted in acylinder e, affixed to thelrafme .chaine machine, and is provided withports ,fi/"done near its lower andv itheothcr near its upper end. Saidports communicate with a valve-cylinder 71., which contains a doublepuppet-valve composed of two heads n" anda connecting-stellig'.

In the constructies; shown-:in required to press theslide s toward the throat Fig. 1 the chute or staple-holder-isstraight,n, the slide being adapted to move baci; and and the feeding-slide s isprovided with rollforth in the arc et a circle on. the segmental chute'lhr rear end ol the slide iff. made `ers t t', arranged to run the oneon the upper wedge-shaped, as shown at s s', Figs. 7 and '8,

and-when thewslidcv is moved back it enters the space between the cars 09 and forces-'said ears apart, as shown in Fig. 7, thereby releasing thechute q. The slide s has recesses 17 17, which are engaged byprojections 1S '1S on the ears 9 9, the slide being thus held in saidears until the chute is reinserted between them.

From the foregoing' it willjbe seen that the operator is enabled toholdlthe machine in one hand and present the throat a, at any pointwhere it is desirable to estafa'steiiing in the edge of a boot or shoeupper, during the operation of lasting, the fastening being driven byeach upward movement of thevalve' of the pneumatic driving device.

I have here shown the throat a formed asy a jaw which is serrated a`ene, side, and `1n' connection therewith I shi wl: a movable jaw 18,which is pivoted at 19 and has an arm or lever 20 arranged to be actedupon by a lever 21,'which is pivoted at 22 to the supporting` frame,said lever 21 being located in such relation to the part 23 of the framewhich serves as the handle of the machine that the operator can graspsaid handle and move the lever 21 in the direction required to close thejaw 1S upon the throat or jaw e..

24 represents a foot which is attached to the frame of the machine, andis arranged in such relation to the jaws a and 1S that it is adapted toserve as a fulcrum-bearing on the inner sole while the upperris beingdrawn by saidI jaws over upon the bottom of the inner sole, the relativearrangemcij" e'rtlieia'fvs ct and .i8 and foot 24 being thelsanlie asthat of the jaws and foot or fulcrum of an ordinary pair oflasting-pincliers- The operator is enabled by the described jaws andfoot to draw thel edge of the upper over upon the bottom of theTsole andthen fasten said edge to the innbrisole by operating the drivingmechanism, as above described, while the edge is being held 'by thejaws, the fastening being drij'ven through the fixed jaw close to thepointwhere the upper is grasped by the two jaws. [iA spring 25,interposed between the jaws a and 18, normally forces the latter back,as shown.

My invention is not limited to the use of the jaws and foot, andthemachine can be used without the same. lVhen the jaws and foot are notused, the cylinder e maybe utilized as the handle of the machine, inwhich case the handle portion 23jwill not be required.

The forward portion of the chute q is provided with side pieces 27 27,.nlffl., extend across the slot q and hold the divisions of the chuteformed by said slot so that neither can spring away from the other. Saidpieces 27 are cut away at their inner sides, as shown in Fig. 4, topermit the legs of the staple to pass them. I. l

Referring tothe construction shown in Fig. l, the latch 3 has adownwaidly-projeeting lller l. on the slide .s lie slide is moved tothesrearff jl. ci the clrnte. Said `rollerI en- -rions points, accordingto the discretion oi' the operator, and, although I haveparticularlydescribed its use in` lasting boot and shoe..uppersylidenotlimit it to such use, but

may use it tor tackin'guon tap-soles or for :other like purposes.

When the valve o't the pneumatic operating device is at its lowestpoint, one side ot' j its lower head e' bears on an inwardly-pro`jecting seat or lip /1/ at the lower end of the cylinder 7.-. andprevents any escape of air through. that-'Lend of the cylinder. At theupper end ot' the cylinder is another seat Il?, which co-operates inlike manner with the head t" in preventing the escape of air through theupper end of the cylinderwheu the valve is at its highest point. Thecylinder 71. is internally reduced in diameter at its upper portion tocorrespond with the reduced diameter of the upper head il', saidreduction being effected `in this case by a lining-tube 713 inserted 'inthe cylinder, the upper portf being foi-ined partly in said tube. Theseat 7g3 may be omitted', as the valves t' l1I only remain raiseil whilethe operator holds the le ver m.l u llence the valve t" seldom reachesthe seat/1i. tigt im i c. cg represent yielding .buffers or washers inthe ends of the cylinder c to cushion the piston as it roaches the en dsof its stroke. 'lhe washer c is annular and serves as a packing toprevent theleakagc ot' air around the drh er-bar` c",
